The changes in this PR are related to the array assignments with the maunal
cur
filtering.For example, some of the existing codes perform the filtering by
| grep "^$cur"
. However, this does not work when$cur
contains special characters of the regular expressions. We try to replace such a code with the regular filtering by the_comp_compgen_split
. (This may change the existing behavior when the user actually expects the filtering by the regular expressions.)Some of the codes seem to have a reason for the manual filtering. I keep the existing manual filtering for such a case, but we might need some discussions to switch to the filtering by
_comp_compgen
.
