There is no need for a counter, nor an old counter to compare it with.

memory: don't bother making a snug fit for things that will be freed soon
...
Most full paths are needed only temporarily and will be freed within
milliseconds. Only 'full_operating_dir' and 'backup_dir' continue to
exist for the whole current session. Any partition, too, will soon be
unpartitioned, so the extra reallocation is just a waste of time.

tweaks: delete some obscuring debugging stuff

When wanting to debug something, it is far more useful
to temporarily insert lines like:
statusline(ALERT, "name = %i", variable);
It provides instant feedback, and it slows things down,
so you can kind of see what happens.

...
(The variable 'pletion_line' is not conditionalized with this option, as
it would become messy. The compiler will probably be able to elide it.)
When using --enable-tiny, it is not possible to use --enable-wordcomp,
because the word completion function uses the undo system.

new feature: complete a fragment to a longer word found in the buffer
...
Executing the 'complete_a_word' function will search from the start
of the current buffer for entire words that begin with the fragment
that is before the cursor, and will complete this fragment to the
first word that is found. Each consecutive call of 'complete_a_word'
will search for the next matching word and will complete the fragment
to that. By default the function is bound to the ^] keystroke.

or lines by holding down Shift together with the movement keys.

To work around some of those, the combinations Shift+Alt+Left/Right work
as Shift+Home/End and Shift+Alt+Up/Down work as Shift+PageUp/PageDown.)
