Subject: Don't treat ' as a string delimiter in RPM spec files
X-Git-Tag: emacs-26.0.90~521^2~294

Don't treat ' as a string delimiter in RPM spec files

' is commonly used as an apostrophe in the prose sections of spec
files, which was erroneously highlighted as strings. See for example
http://kmymoney2.sourceforge.net/phb/rpm-example.html

* lisp/progmodes/sh-script.el (sh-mode-syntax-table): Treat ' as
  punctuation in RPM spec files.
