Fix few typos reported from Fossies.

Fossies administrator Jens alerted me to some typos.

* txr.1: Fix two instances of alphanumeric being hyphenated,
and one case of invocable being rendered as invokable.

* linenoise/linenoise.c (struct lino_state): Misspelled
"buffer" in a comment. One other comment typos in this file is
from the original code, so it stays: who needs yet another
merge conflict? Not touching the original typo in example.c,
either.
