"-e" showing up in message

[mattsawyer77]

I installed the hook and hipchat-cli. Now when I push, I see this (which I'm unsure whether is related to the problem):

...

The push succeeds, yet in my Hipchat window, I see a "-e" in front of each line in the message, like this:

-e Matt Sawyer pushed to branch master of samplerepo.git
-e - testing git-hipchat integration (975b2c7)

This should be the same as the issue mentioned in f22dc0f, I'll check. Your repo server OS?

[mattsawyer77]

Debian Squeeze.

Switching to /bin/bash works. The "-e" option isn't support in /bin/sh, so it's being echoed out as text.

I think the -e option is implicit when echo is used inside scripts (as opposed to directly in the command line). I've removed it from all echo commands in the hook and it is working perfectly. I've tried commit messages with special chars and they are treated like the -e option was been used.
