Details:

Using hdata_update to change the last line's prefix crashed Weechat. The
test.lua script and gdb backtrace are in the attachments.

If I use the same script to change message or date, it works fine.

Also, some people have informed me to not use hdata to change stuffs (as it
already says modification is forbidden in the top of hdata section of plugin
docs), but the doc for hdata_update shows an example of python script changing
the date of last line. If it's forbidden, I think that script example should
be gone since it will confuse people or may be just make that function
unavailable to script.

If modification is allowed but not prefix, then prefix should be removed from
"List of hdata -> line_data -> Update allowed".
