i18n: check equality of initial indentation between msgid and msgstr

Document generation by runrst in "doc" directory may succeed silently,
even though initial indentation is different between msgid and msgstr:
for example, it may be unexpected or missing indentation.

This patch adds the checker to check equality of initial indentation
between msgid and msgstr.

This checker is categorized as "warning" level, because problem
detected by this is not so serious for usual Mercurial usage.

Update to link without local change should get us a symlink (issue3316):

  $ hg up
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Update to link with local change should cause a merge prompt (issue3200):

Test merge with no common ancestor:
a: just different
b: x vs -, different (cannot calculate x, cannot ask merge tool)
c: x vs -, same (cannot calculate x, merge tool is no good)
d: x vs l, different
e: x vs l, same
f: - vs l, different
g: - vs l, same
h: l vs l, different
(where same means the filelog entry is shared and there thus is an ancestor!)
