With the current version of the mu server, it is not possible open
attachments, because the server expects symbols as parameters, but
mu4e sends strings.
This change fixes this.
In the keybinding defintions for mu4e-view-mode-map, the variable
mu4e-view-use-gnus was used quoted in an if condition, which means that the
condition always evaluated to true. Therefore, M-q would always be bound to
article-fill-long lines and never to mu4e-view-fill-long-lines.
Use "_" as the title of that section so that it is less distracting
when sections are collapsed to get an overview of the library.
Using a separate section is useful because it reduces the risk of
accidentally into the middle of a library.
Placing two semicolons on an otherwise empty line helps to logically
"connect" the surrounding "paragraphs", which in (only) some cases
makes sense.
Previously the three paragraphs of the permission statement were not
connected to each other like this, which is perfectly fine. However
the preceding "This file is not part of GNU Emacs." line was connected
to the first paragraph, which does not make sense considering that the
latter is not connected two the second paragraph, which it relates to
more.
Once those two semicolons are gone, it also makes sense to remove
those from the second line.
Commit edce635416 only loads it
dynamically when executing the function mu4e~view-gnus but as a
consequence many variables are undefined at compile time and, more
importantly, it is no longer possible to override the variable
gnus-display-mime-function with a let binding before calling
gnus-article-prepare-display
Disable some of the key-binding that don't quite work for the gnus-based
view. We'll probably want a gnus-view specific set of bindings, but at
least for now avoid the errors.
Previously both cl-lib.el and cl.el were used, now use only cl-lib.el.
Use lexical-binding where needed instead of requiring cl just for
`lexical-let`.
Replace some add-to-list with cl-pushnew as add-to-list is not
recommended in lisp program and anyway doesn't work properly with
lexical binding.
This is a bit of hack, but solves the problem; even when not _showing_
the attachments-header, construct the corresponding map, so the
keybindings work.
Mark some variables as use permanent-local so they'll survive a
major-mode change. Activate mu4e-view later, so hooks have some more
material to work with.
