*
* * subversion/clients/cmdline/util.c
* (svn_cl__edit_externally): Clean up the "no external editor"
* error message.
* (svn_cl__get_log_message): Wrap "no external editor"
* errors with helpful hints about the -m and -F options.
*
* * subversion/libsvn_client/commit.c
* (svn_client_commit): Actually capture and propogate "no external
* editor" errors.</msg>
