store: encode first period or space in filenames (issue1713)
- Mac OS X has problems with filenames starting with '._'
(e.g. '.FOO' -> '._f_o_o' is now encoded as '~2e_f_o_o')
- Explorer of Windows Vista and Windows 7 strip leading spaces of
path elements of filenames when copying trees
Above problems are avoided by encoding the first space (as '~20') or
period (as '~2e') of all path elements.
This introduces a new entry 'dotencode' in .hg/requires, that is,
a new repository filename layout (inside .hg/store).
Newly created repositories require 'dotencode' by default. Specifying
[format]
dotencode = False
in a config file will use the old format instead.
Prior Mercurial versions will abort with the message
abort: requirement 'dotencode' not supported!
when trying to access a local repository that requires 'dotencode'.
New 'dotencode' repositories can be converted to the previous
repository format with
hg --config format.dotencode=0 clone --pull repoA repoB
