hotspot showed that 0.15% of the KMComposerWin constructor is spent
here because setText() emits dataChanged, that's easy to remove.

CCBUG: 425081

The default QTextEdit behavior is following:
 - the current char format corresponds to the symbol right _before_ the cursor position.
 - if the cursor is at the start of the block, the format is grabbed from the symbol _after_ the cursor.

It works well with standard formatting (bold, underline, etc), which can easily be enabled / disabled using corresponding QActions.
Note that the behavior is also the same for, say, LibreOffice.

However, it does not work well with hyperlinks. If the document ends with a link, it is virtually impossible
to start typing normal text right after this link (i.e. to reset the char format). The only way to do it
is to use copy-paste (i.e. paste some normal text, preserving formatting), which is quite frustrating.

For the same reason it's not easy to write some text right after hyperlink.
I believe it's the reason behind this tiny whitespace in `insertHtml` inside richTextComposer.

The workaround is following: alter the default behiour and take the character format from symbol right _after_
the link if the cursor points at the end of the link (this is also the way LibreOffice behaves).
