Convert pnmatch to single element array in regexec calls

Browse Source 
The regexec function is declared as taking an array of regmatch_t
elements, and passing in the pointer to singleton element, while
correct, triggers a Coverity warning. Convert the singleton into
an array of one to silence the warning.
