[elpa] externals/idlwave 3db3ab7046 066/360: Patches from Stefan Monnier:

[ELPA Syncer]

branch: externals/idlwave
commit 3db3ab704673111faf3edbd1ba3f1f371255e6f7
Author: jdsmith <jdsmith>
Commit: jdsmith <jdsmith>

    Patches from Stefan Monnier:
    
    Add a \ in front of open-paren-in-column-0 in docstrings.  Otherwise
    indentation and font-lock get confused.
    (idlwave-function-menu): Use defalias so the funs are called interactively.
    Don't rely on knowledge about which Emacs provides imenu or func-menu.
    (idlwave-calculate-cont-indent): Fix typo.
    (idlwave-font-lock-keywords-*): Don't use setq on a defconst.
    Remove unused variables.
