color: stop mutating the default effects map A future change will make color.setup() callable a second time when the pager is spawned, in order to honor the 'color.pagermode' setting. The problem was that when 'color.mode=auto' was resolved to 'win32' in the first pass, the default ANSI effects were overwritten, making it impossible to honor 'pagermode=ansi'. Also, the two separate maps didn't have the same keys. The symmetric difference is 'dim' and 'italic' (from ANSI), and 'bold_background' (from win32). Thus, the update left entries that didn't belong for the current mode. This bled through `hg debugcolor`, where the unsupported ANSI keys were listed in 'win32' mode. As an added bonus, this now correctly enables color with MSYS `less` for a command like this, where pager is forced on: $ hg log --config color.pagermode=ansi --pager=yes --color=auto Previously, the output was corrupted. The raw output, as seen through the ANSI blind `more.com` was: <-[-1;6mchangeset: 34840:3580d1197af9<-[-1m ... which MSYS `less -FRX` rendered as: 1;6mchangeset: 34840:3580d1197af91m ... (The two '<-' instances were actually an arrow character that TortoiseHg warned couldn't be encoded, and notepad++ translated to a single '?'.) Returning an empty map for 'ui._colormode == None' seems better that defaulting to '_effects' (since some keys are mode dependent), and is better than None, which blows up `hg debugcolor --color=never`.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version
