to process generated HTML. This not cause any side effects except
leaving some character entities in their numeric form instead
converting them into alphabetical notation (< instead of <),
but since all browsers understand such cases it is not a problem.
This commit should make all translations tidy clean, since
tidy should not arise entities conversion problem as it did
for long time before. Therefore all occurences of manual settings
of TIDYFLAGS and NO_TIDY declarations for translations are removed.
Also clean *OPTS/*FLAGS variables declaration like it was done in doc/ tree
some time ago. Currently all local additions to commands parameters that used
in make process should be passed thru *FLAGS variables. All variables
with OPTS suffix are reserved for internal use of web.site.mk now.
Cleanup part is based on work done by Cyrille Lefevre <clefevre-lists@noos.fr>
No objections from: -doc
Requested by: Russian and Japanese translation teams
