( If that's right, would it be reasonable to make ash ignore them too -
it would allow easier porting to ash from bash. )
I must admit I had mistakenly thought that the way of invoking functions
with parameters in bash required use of round brackets, but I now see it
isn't so.
Are you sure? From "man bash":
[ function ] name () compound-command [redirection]
There is no indication of "()" being optional. Actually it would be
interpreted as a call of "func2", followed by other statements, so it's
not possible to define a function this way.
On the other hand, "help function" says:
function name { COMMANDS ; } or name () { COMMANDS ; }
so "()" may be optional after the keyword "function".
Actually this contradicts each other, because according to the manual,
"()" is required, while according to the help, it is not allowed.
