bug#44451: 27.1; doc string of `read-char-from-minibuffer'

 "Read a character from the minibuffer, prompting for PROMPT."

You are not prompted for PROMPT.  You are prompted (for a char)
with PROMPT.

 "When HISTORY is a symbol, then allows navigating in a history."

English: it should be "When...symbol, allow navigating..."

But it's not clear what "navigating in a history" means.  The
description of `M-n' etc. isn't clear - or needed.  And what if
HISTORY is non-nil but not a symbol?

In any case, I suggest you just say that HISTORY is passed to
`read-from-minibuffer', which is the case.  That function's HISTORY
description is clear and complete, and it involves more than what is
described here.
