Update doc string.
(face-attribute-name-alist):
Add :inherit.
(face-valid-attribute-values):
Handle :inherit.
(face-read-string):
Rephrase prompt to be less confusing.
Assume that DEFAULT is a string, since we must return a string.
(face-read-integer):
Use `format' to turn DEFAULT into an acceptable default for face-read-string.
Match NEW-VALUE against the string "unspecified", not the symbol
`unspecified', since that's what face-read-string returns.
(read-face-attribute):
Lookup a name for old-value in valid, and use it as a default if we find one.
Treat all values from face-read-string as strings.
If the default is used, don't do any more processing on the value,
just use the old value directly.
(read-face-and-attribute, modify-face):
Tweak prompt.
(read-face-name):
Don't assume prompt ends with a space.
(mode-line, header-line, tool-bar): Same default as x for w32.
(fixed-pitch, variable-pitch): Remove wildcard as it prevents
face-font-family-alternatives from working.
(set-face-attribute): Purecopy args.
(read-face-name): Default to name at point and use it in prompt.
Remove colon from arg in all callers.
(list-faces-display): Hyperlink to face descriptions and customize
buffers.
