I think you're crazy to think shells are more likely to have conflicts.
Shells require a whole token match, not just the first letter.
In other words, any alias *starting with* the letters c, d, e, f, g, h, i,
o, s, w, z would be a conflict. Just for maximum confusion the list of
letters which cause conflicts when capitalized would be entirely
different.
Picture a newbie typoing on their \old alias and trying to figure out
where all their data is going... Hopefully they weren't too attached to
whatever was in their "ldd" file yesterday.
Of course, the patch doesn't work this way. Only complete tokens delivered
by the parser are substituted, illustrated here with your example:
#= \alias old SELECT version();
#= \old
version
