dirstate: introduce function to normalize just filenames This will be used in upcoming patches to stop generating the set of directories in many common cases.

dirstate: factor out code to discover normalized path In upcoming patches we're going to reuse this code. The storemap is currently always the foldmap, but will vary in future patches.

dirstate: don't require exact case when adding dirs on icasefs (issue4578) We don't require it when adding files on a case insensitive filesystem, so don't require it to add directories for consistency. The problem with the previous code was that _walkexplicit() was only returning the normalized directory. The file(s) in the directory are then appended, and passed to the matcher. But if the user asks for 'capsdir1/capsdir', the matcher will not accept 'CapsDir1/CapsDir/AbC.txt', and the name is dropped. Matching based on the non-normalized name is required. If not normalizing, skip the extra string building for efficiency. '.' is replaced with '' so that the path being tested when no file is specified, isn't prefixed with './' (and therefore fail the match).

filemerge: clean up language in mergemarkertemplate help

color: fix crash in cmd.exe When 'term' is None because it isn't in the environment, don't iterate over it. Unfortunately, unsetting $TERM or exporting it as '' doesn't work in the tests, so there's no way to simulate cmd.exe in the test suite.

log: prefer 'wctx' over 'pctx' for working context

tags: remove scary message about corrupt tags cache Caches should be transparent. If a cache is damaged, it should silently be rebuilt, much like if it were invalid. No one seems to have ever hit this in the wild.

hgk: use switch instead of a less efficient if/elseif/if

hgk: set distinct fill and outline colour for non-public and obsolete changesets
