You are right, and my patch does exactly what you want.

Before this patch, the regular expression looked like
"move[ \t\n]*" and used case-insensitive comparison inside regexec,
i.e. it called tolower/toupper, which are locale dependent.

With the patch, the regular expression looks like
"[mM][oO][vV][eE][ \t\n]*" and uses case-sensitive comparison inside
regexec, i.e. no locale dependent calls. Also the conversion from
"move" to "[mM][oO][vV][eE]" uses the macros from "safe-ctype.h" which
are locale independent.
