Changes:
* progmodes/make-mode.el: Bring it up to date with makepp V2.0.
* ses.el: The overall change is to add cell renaming, that is
setting fancy names for cell symbols other than name matching
"\\`[A-Z]+[0-9]+\\'" regexp .
* progmodes/gdb-mi.el (gdb): Set comint-prompt-regexp, required
for completion via gud-gdb-fetch-lines-filter (Bug#10274).
* mail/rmailsum.el (rmail-header-summary): RFC2047 decode the
`from' or `to' address before taking its substring. Fixes
incorrect display in Rmail summary buffer whereby an RFC2047
encoded name is chopped in the middle of the encoded string, and
thus displayed encoded.
* speedbar.el (speedbar-supported-extension-expressions):
Add .adb and .ads, commonly used for Ada source code (bug#10256).
