[PATCH 1/3] [EXCEPTIONS] Stop documenting EXSHELLPROC

[Jonathan Nieder <jrnieder@xxxxxxxxx>]

At some point between ash 0.3.5-11.0.1 and ash 0.3.8-37, Debian
ash stopped using the EXSHELLPROC exception to handle shell
scripts without a magic number.

Remove all remaining references to it to avoid confusion.
