Nice. This regexp '(^|/)[.][^/]+[.]sw[a-p]$' is a clear improvement over
the
(much) simpler one "\\.sw.$" from my PR (which was mostly about adding
"^(GPATH|GRTAGS|GTAGS)$" for the GNU Global source tagger) as it
covers both
top-level and subdirectories and hence avoids hitting *.swf or *.swc files.
I trust you checked that 'perl = TRUE' applies also to these entries
from
tools:::get_exclude_patterns() ?
