Some user interaction with git-p4 is not as user-friendly as the rest of the
Git ecosystem. Here are three areas that can be improved on:

1) When a patch fails and the user is prompted, there is no sanitization of
the user input so for a "yes/no" question, if the user enters "YES" instead
of a lowercase "y", they will be re-prompted to enter their answer.

Commit 1 addresses this by sanitizing the user text by trimming and
lowercasing their input before testing. Now "YES" will succeed!

2) Git can handle scraping the RCS Keyword expansions out of source files
when it is preparing to submit them to P4. However, if the config value
"git-p4.attemptRCSCleanup" isn't set, it will just report that it fails.

Commit 2 adds a helpful suggestion, that the user might want to set
git-p4.attemptRCSCleanup.

3) If the command line arguments are incorrect for git-p4, the program
reports that there was a syntax error, but doesn't show what the correct
syntax is.

Commit 3 displays the context help for the failed command.

Ben Keene (4):
  git-p4: yes/no prompts should sanitize user text
  git-p4: show detailed help when parsing options fail
  git-p4: wrap patchRCSKeywords test to revert changes on failure
  git-p4: failure because of RCS keywords should show help
