Thank you. For some reason however, the seconde run of `export LANC=C;
enable -r else; if true; then echo 'yep'; else echo 'nop'; fi; disable
-r else` will return an error message with the system local anyway:
% enable -r else;
% export LANC=C; enable -r else; if true; then echo 'yep'; else echo
'nop'; fi; disable -r else
yep
% export LANC=C; enable -r else; if true; then echo 'yep'; else echo
'nop'; fi; disable -r else
yep
zsh: else: commande inconnue.

I'm rather estonished by this lake of possibility to make the equivalent
of an "\n" in the middle of a line, but OK.
So the idea would be to have something like
% whence -w else
else: reserved
% enable -r else; "\n" whence -w else; if true; then echo 'yep';
else echo 'nop'; fi; disable -r else
else: reserved
yep
% whence -w else
else: none
% enable -r else; "\n" whence -w else; if true; then echo 'yep';
else echo 'nop'; fi; disable -r else
else: reserved
yep
But "\n" doesn't work here as a substitution of an effective linefeed.

Nice to know, thank you.
