- all possible completions have the same case
Ordinary completion preserves input case only where the potential completions differ in case. If they agree then ordinary completion changes the input case to that of the prefix.
For example, evaluate:
(partial-completion-mode 0)
(setq completion-ignore-case t)
(completing-read "Input: " '(("Den".1)("Denis".2)) nil t "d")
Hitting TAB runs ordinary "minibuffer-complete" which completes "d" to "Den" (case corrected).
Enable partial completion:
(partial-completion-mode 1)
Re-evaluate the above completing-read.
Hitting TAB now runs "PC-complete" which completes "d" to "den" (fails to correct input case).
I've tested the attached patch thoroughly. Please contact me if you want any more background on this.
