Subject: git-quiltimport: better parser to grok "enhanced" series files.
X-Git-Tag: v1.5.5-rc0~2^2~7^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=9dd5bded1bdc4f518aeed6a32ad70ccdd182dde5;p=git.git

git-quiltimport: better parser to grok "enhanced" series files.

The previous parser wasn't able to grok:

 * empty lines;
 * annotated patch levels (trailing -pNNN annotations);
 * trailing comments.

Now it understands them and uses the patch level hints as a git apply
argument.
