Re: [PATCH] use .zwc files with identical timestamps

Any opinions on this?

Note that this might also fix the issue reported in zsh-workers/41396:

| I extract functions from .plugin.zsh files, then compile them as
| digest: zcompile -Uz lexicon.zwc functions/*
If that compilation is done immediately after the extraction, then in
most cases the .zwc files would never actually be used as they'd have
timestamps identical to those of the source files.
