vim-patch:8.2.4475: fuzzy cmdline completion does not work for lower case

Browse Source 
Problem:    Fuzzy cmdline completion does not work for lower case.
Solution:   Also use fuzzy completion for lower case input. (Yegappan
            Lakshmanan, closes vim/vim#9849)

4df5b33f20

Initialize "regmatch" to avoid using uninitialized memory.
