[PATCH] splicemap: support for path with spaces in splicemap (issue3844)

[Szymon Wróblewski]

> Patch doesn't apply cleanly (appears to have some mailer-induced damage). Please consider using the patchbomb extension <http://mercurial.selenic.com/wiki/PatchbombExtension>.

I forgot to send mail in plain text mode in gmail. Sorry. I'll try to
use Patchbomb extension next time.

> When re-sending, we also generally use the --flag option to mark a patch/series V2, V3, etc.

For the sake of discussion continuation I'll use reply for the last
time. As I understand future patch versions should be sent as a new
thread with [PATCH Vx] in topic, right?

> As mentioned on <http://mercurial.selenic.com/wiki/CodingStyle>, we vaguely follow PEP8 where whitespace and line length are concerned:

I know, that is why I corrected recently accepted code in repo to
follow PEP8 specification.


Without further talking, here is latest patch again.

splicemap: support paths with spaces in splicemap (issue3844)

Shlex module was used to split line as suggested. Split operates in POSIX mode.
