windows: handle spaces in path to Python (issue2074)

minirst: pull admonition titles out formatblock function

minirst: refactor/simplify findblocks

inotify: raise correct error if server is already started in a deep repository When path is too long to be an Unix socket address, we create a socket in a temporary directory and link from the long path to the shorter one. But checks in server code at startup were insufficient in this case, and used to raise an unclear "tried linking .hg/inotify.sock to a temporary socket but .hg/inotify.sock already exists"

setup: user-friendly error message if Python headers are missing

test-keyword: ignore subject in notify hook mails Long tmpdir names caused truncation of subject anyway, and that made $TESTTMP replacement fail.

test-keyword: fix test glob to ACL/SELinux flag

test-notify: fix fix for line continuation in long mail header lines Continued lines can also start with space. Note that this hack also incorrectly patches the diff output.

import: don't strip '#' lines from patch descriptions (issue 2417) Previously no '# ' lines came through the parser. Now only the first '# ' lines are processed, from '# HG changeset patch' and to the first line not starting with '# '.

test-notify: stabilize output test-notify is made a bit more stable by stripping "all" folders away instead of just 3.

tests: reintroduce ":$HGPORT" in test output This reduces the number of patterns that must be adjusted when writing tests.

tests: remove the last traces of $HGTMP $HGTMP isn't needed - and if we need something like that then $TESTTMP is more appropriate.
