This is because the proper usage of skip_prefix() overrides the functionality of starts_with(). Thorough replacements may finally remove the starts_with() function and reduce  code redundency.

Justifying a change is certainly a good idea, however, the above
reasoning for this particular change is off mark. See below.

Also, wrap commit message lines to 65-70 characters or so.

This actually makes the code more difficult to read and understand.
There's a more fundamental reason to use skip_prefix() here. See if
you can figure it out. (Hint: shortname)

This sort of commentary, which is appropriate to the email discussion
but not meant for permanent project history, should be placed
immediately below the "---" line following your sign-off.
