py3: don't run source transformer on hgext3rd (extensions) It's unclear why the source transformer runs on hgext3rd. It's been like that since it was introduced in 1c22400db72d (mercurial: implement a source transforming module loader on Python 3, 2016-07-04), and that commit didn't say anything about it (but it says that it doesn't have "support [...] for extensions"). I find that the current handling of hgext3rd just makes it harder to convert extensions to Python 3. It makes you convert a bunch of strings passed to getattr() and kwargs[] to r'' that could otherwise have been left alone. It's also really confusing that the source transformer runs when you import the extension as "extensions.foo=", but not as "extension.foo=/some/path". I suppose there is small number of (very simple) extensions that would have worked without this patch that would now be broken. It seems okay to me to break those.

crecord: provide 'X' as a range-select mechanism Differential Revision: https://phab.mercurial-scm.org/D6621

crecord: make KEY_ENTER usable in tests (by not updating UI) Differential Revision: https://phab.mercurial-scm.org/D6620

crecord: fix if -> elif when handling key presses This shouldn't actually change any behavior, I only noticed it since I started using KEY_UP in tests, and it was complaining when it got down to the ^L handler that initscr hadn't been called yet.

graft: moved abortgraft and readgraft to cmdutil This patch moves `abortgraft` and `readgraft` to `cmdutil`. Various callers are updated accordingly. This is done because these serve as ulitlity functions for command `graft` and so that new functions regarding graft can be built from them.

cleanup: use named constants for second arg to .seek() Differential Revision: https://phab.mercurial-scm.org/D6556

patch: use a short, fixed-size message for last line of prompt (issue6158) See issue6158 and the previous commit for examples of what might go wrong if we have some combinations of readline version and terminal and need to wrap the line. Briefly: readline may not display the beginning of the last line of the prompt, or it may print over it with the end of the prompt, making it difficult for users to know what's going on.

filemerge: make last line of prompts <40 english chars (issue6158) I've chosen <40 as the target so that other languages that may have a 2x blowup in character count can still have a chance to fit into an 80 column screen. Previously, we would show a prompt like: ``` keep (l)ocal [dest], take (o)ther [source], or leave (u)nresolved for some/potentially/really/long/path? ``` On at least some systems, if readline was in use then the last line of the prompt would be wrapped strangely if it couldn't fit entirely on one line. This strange wrapping may be just a carriage return without a line feed, overwriting the beginning of the line; example (100 columns wide, 65 character filename, and yes there's 10 spaces on the end, I assume this is to handle the user inputting longest word we provide as an option, "unresolved"): ``` ng/dir/name/that/does/not/work/well/with/readline/file.txt? ave (u)nresolved for some/lon ``` In some cases it may partially wrap onto the next line, but still be missing earlier parts in the line, such as below (60 columns wide, 65 character filename): ``` rev], or leave (u)nresolved for some/long/dir/name/that/do s/not/work/well/with/readline/file.txt? ``` With this fix, this looks like this on a 60 column screen: ``` tool vim_with_markers (for pattern some/long/dir/name/that/d oes/not/work/well/with/readline/file.txt) can't handle binar y tool meld can't handle binary tool vim_with_markers can't handle binary tool internal:merge3 can't handle binary tool merge can't handle binary no tool found to merge some/long/dir/name/that/does/not/work /well/with/readline/file.txt file 'some/long/dir/name/that/does/not/work/well/with/readli ne/file.txt' needs to be resolved. You can keep (l)ocal [working copy], take (o)ther [merge rev ], or leave (u)nresolved. What do you want to do? ``` Differential Revision: https://phab.mercurial-scm.org/D6562
