- Improve function name: parse_rule -> parse_filter_str (to make the
similarity with parse_filter_file clearer, and better indicate that
it can parse multiple rules when FILTRULE_WORD_SPLIT is specified).
- In preparation for rule prefixes containing information beyond the
rflags, change the code to pass around a full "template" filter_rule
instead of just rflags. Callers of parse_filter_{str,file} that want
to specify only rflags can use rule_template(rflags) .
- Remove the MODIFIERS_* strings and instead hand-code the condition
under which each modifier is valid. This should make it easier to
see that the conditions are correct.
- Tighten up default modifiers on merge rules:
- Disallow "!" because it isn't useful.
- If the merge rule specifies a side via "s" or "r", the rules in the
file cannot also specify a side via "s", "r", "hide", etc.
[Patch was changed by Wayne a bit prior to application.]
- Free a mergelist's parent_dirscanned filters the last time it is
popped or as soon as the filters are discarded due to the "n"
modifier. Aside from not leaking memory, this is needed to clean up
any mergelists defined during the parent_dirscan to avoid crashing by
trying to restore nonexistent state for them in pop_local_filters.
- Make push_local_filters save the current mergelist_cnt, and make
pop_local_filters assert that it has the correct number of mergelists
before restoring their state.
- Assert that mergelists get deactivated in strict LIFO order to catch
any glitches as soon as they happen. Free linked lists of filters in
reverse order to make that the case.
- Add a bunch of mergelist-related debug output (--debug=filter2).
- Remove the trailing slash earlier, so that it doesn't
affect the XFLG_ABS_IF_SLASH check.
- Count the slashes earlier so that the XFLG_ABS_IF_SLASH
can use it instead of using a strchr() all that could
scan past the end of the input.
- Removed the CFN_KEEP_LEADING_DOT_DIR flag for clean_fname().
- Explicitly add an implied dot-dir to the transfer rather than keeping
a leading a "./" prefix as a part of a relative pathname.
- Added the CFN_KEEP_DOT_DIRS flag for clean_fname().
- Added the SP_KEEP_DOT_DIRS flag for sanitize_path().
- Call clean_fname() a couple more times.

- If ignore_perishable is set, we ignore all perishable rules.
- Mark all default-cvsignore rules as perishable (e.g. excludes such
as *.o CVS .svn/ will not prevent a directory from being deleted).
