[PATCH 0/3] stripspace: Implement and use --count-lines option

This patch set implements some of the project ideas around git stripspace suggested on [1].

[1] https://git.wiki.kernel.org/index.php/SmallProjectsIdeas

The first patch moves the stripspace() function to the strbuf module (adding a prefix and changing all users accordingly, also a wrapper is introduced in case any topic branches still depend on the old name). The second patch introduces option --count-lines to git stripspace and also adds documentation and tests accordingly, Finally, the third patch changes git-rebase--interactive.sh to replace commands like:

	git stripspace ... | wc -l

with:

	git stripspace --count-lines ...

Tobias Klauser (3):
  strbuf: make stripspace() part of strbuf
  stripspace: Implement --count-lines option
  git rebase -i: Use newly added --count-lines option for stripspace
