I don't know.  I don't see any significant lag here.  But if that's
a problem, maybe we should tweak the system so we only fetch the list
when there's at least one char after the space (to keep the list
shorter)?

The OP mentions Emacs crashing, which points to another problem than
mere lag.  I can't investigate this because I can't reproduce it here
on Debian.

And maybe it depends on the system (or more specifically on what kind of
`man` program is installed and how it supports `man -k`; e/g. if
there's no prebuilt index and `man -k` scans through all the installed
troff pages every time)?
