trydiff: make addindexmeta() unconditionally add index meta The conditional-ness is not clear from the name and there is only one caller, so it's clearer to check on the call site. Moving it also makes addindexmeta() no longer close on the 'opts' variable.

trydiff: remove unused code for git index of "combined diff" We only ever produce diffs with one pre- and one post-image, so remove the code for displaying "index" lines for combined diffs.

diff: remove dead assignment

localrepo: show headline notes in commitctx before showing filenames commitctx already showed notes with filenames but didn't provide any context. It is just as relevant to know when manifest or changelog is committed. So, in addition to filenames, also show headlines 'committing files:', 'committing manifest' and 'committing changelog'.

bundle: when verbose, show what takes up the space in the generated bundle This is kind of similar to the debugbundle command but gives summarized actual uncompressed number of bytes when creating the bundle. The numbers are as usable as the bundle format is efficient. Hopefully bundle2 will make it a better indicator of actual entropy. This is useful when accepting pull requests to assess whether the repo size increase seems reasonable for the diff before pushing stuff upstream, It has helped me catching large files that should have been committed as largefiles but was committed as regular files in intermediate changesets. This output doesn't combine well with debug output so we only enable it when verbose without debug.

setdiscovery: factorize similar sampling code We are using full sampling of 'fullsamplesize' in both case. The only difference is the debug message. So we factorise the sampling code and put the message in an extra conditional. This is going to help making changes around the sampling logic. Such changes are needed to improve discovery performance on highly headed repository.

setdiscovery: drop shadowed 'undecided' assignment The 'undecided' variable was never used before being overwritten a few lines later.

hgweb: extract changelist entry generation into own function I want to supplement changelist entries (used by shortlog and changelog endpoints) with custom metadata from an extension. i.e. I have extra per-changeset metadata that I wish to make available to templates so it can be rendered on hgweb. To facilitate this, I've extracted the logic for creating a changeset data structure into its own function, where it can be wrapped by extensions. Ideally, hgweb would use the same templater as the command line and have full access to templatekw.keywords. But that's a lot of work. This patch gets us some of the benefit without all the work. Many other hgweb commands could benefit from similar refactorings. I'm going to wait to see how this patch is received before I go crazy on extracting inline functions.

templates: use CSS classes for diff styling Use of inline style for diff styling led to significant browser memory usage on large diffs. Moving the styling into CSS classes corrects this. This patch is based on work from https://bugzilla.mozilla.org/show_bug.cgi?id=766952 and https://hg.mozilla.org/hgcustom/version-control-tools/rev/2c355a580af6

templates: remove unnecessary <span> The <span> on diffline was useless. It was only making browsers work harder. Remove it.
