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

Set up a base, local, and remote changeset, as well as the working copy state.
Files names are of the form base_remote_local_working-copy. For example,
content1_content2_content1_content2-untracked represents a
file that was modified in the remote changeset, left untouched in the
local changeset, and then modified in the working copy to match the
remote content, then finally forgotten.

Check which files need to be resolved (should correspond to the output above).
This should be the files for which the base (1st filename segment), the remote
(2nd segment) and the working copy (4th segment) are all different.

Interestingly, one untracked file got merged and added, which corresponds to the
odd 'if force and branchmerge and different' case in manifestmerge().

Check status and file content

Some files get added (e.g. content1_content2_content1_content1-untracked)

It is not intuitive that content1_content2_content1_content4-tracked gets
merged while content1_content2_content1_content4-untracked gets overwritten.
Any *_content2_*-untracked triggers the modified/deleted prompt and then gets
overwritten.

A lot of untracked files become tracked, for example
content1_content2_content2_content2-untracked.

*_missing_missing_missing-tracked is reported as removed ('R'), which
doesn't make sense since the file did not exist in the parent, but on the
other hand, merged-in additions are reported as modifications, which is
almost as strange.

missing_missing_content3_missing-tracked becomes removed ('R'), even though
the remote side did not touch the file
