 |Yes, I'd like to have that behaviour when original ~/.a is preserved in the

History is a very good reason, indeed.

(In fact i struggle with the same also for expansion of "+" <>
"mail folder", and even manually edited history in the past to
avoid effective duplicates, really.)

 |With my patch it adds it to set +o and set -o level, so it works like this:

 |~ $ echo ~/sr
 |

 |
 |~ $ echo ~/src
 |
 |~ $ set -o expand-tilde
 |~ $ echo ~/sr

 |
 |~ $ echo /home/catap/src/                                          \

Yes, cool, yes.  (That "single expansion" is different to what
you said in January i think it was.)  Great!  I like that.
