mu4e.texi: mention header-line-format misalignment & workaround 

We can't fully fix this with the current headers-view, but this may help
some user. Based on code provided by @phil-s.

Fixes #2606.

@section Known issues
Although they are not really @emph{questions}, we end this chapter with
a list of known issues and/or missing features in @t{mu4e}. Thus, users
won't have to search in vain for things that are not there (yet), and
the author can use it as a todo-list.

@subsection UTF-8 language environment is required
@t{mu4e} does not work well if the Emacs language environment is not
UTF-8; so, if you encounter problems with encodings, be sure to have
@code{(set-language-environment "UTF-8")} in your @file{~/.emacs} (or
its moral equivalents in other places).

@subsection Thread handling is incomplete
While threads are calculated and are visible in the headers buffer,
you cannot collapse/open them.
@subsection Headers-buffer can get mis-aligned
Due to the way the headers buffer works, it can get misaligned.
@subsection Key-bindings are @emph{somewhat} hard-coded.
That is, the main menu assumes the default key-bindings, as do the
clicks-on-bookmarks.
For the particular case where the header values are misaligned with the column
headings, you can try something like the following:
@lisp
(add-hook 'mu4e-headers-mode-hook #'my-mu4e-headers-mode-hook)
(defun my-mu4e-headers-mode-hook ()
;; Account for the fringe and other spacing in the header line.
(header-line-indent-mode 1)
(push (propertize " " 'display '(space :align-to header-line-indent-width))
header-line-format)
;; Ensure `text-scale-adjust' scales the header line with the headers themselves
;; by ensuring the `default' face is in the inheritance hierarchy.
(face-remap-add-relative 'header-line '(:inherit (mu4e-header-face default)))
@end lisp
For a more complete list, please refer to the issues-list in the
github-repository.
This does not solve all possible issues; that would require a thorough rework of
the headers-view, which may happen at some time.
