The `%' character is has a special meaning in Vcs' ,form files (it is
used to form tags like `<%= title %>'). If you forget to escape a
literal `%', Vcs produces abstruse error messages :
[vcs] info: Creating a new `,iform' file ...
[vcs] info: ,form already exists
[vcs] error: Removing `,iform' ...
[vcs] info: ,form: Contains your complete form (title, subject, ChangeLog entry, diff)
[vcs] info: ,log: Contains your Log entry
[vcs] error: compile error
[vcs] error: (erb):3: parse error, unexpected tGVAR
[vcs] error: $erbout_
[vcs] error: ^
Escaping the character with a backslash (`/') solves this problem, but
the backslash is left in the ChangeLog! Is there a right way to get
a literal `%', or a workaround?
