alias: improved diagnostic when arguments include --cwd, etc.
The logic pre-emptively checks for -R, --repo, --repository and --cwd
in order to give the user a more helpful error message. In addition,
each option is handled invididually, which avoids listing them all in
the error.
Before:
% hg --config alias.broken='push --cwd /dev/null' broken
abort: Option --cwd may not be abbreviated!
After:
% hg --config alias.broken='push --cwd /dev/null' broken
error in definition for alias 'broken': --cwd may only be given on the command line
