Don't all symbols then have TEXT type?

Having "BSS-like symbols" in TEXT section would just be weird,
because the point of BSS is that the area is zeroed by OS
when the program starts, unlike with DATA section.

There were few reasons for limiting.  Large C-programs can easily
have thousands of symbols.  Limiting the auto-completion makes
things easier, especially if there are TEXT & DATA symbols with
same names.  It avoid user accidentally using wrong symbol, by
not providing choices that are in most cases bogus.

Note that only auto-completion is limited, the actual disassembly
will still show all symbol types, that are on disassembled addresses 
(instead of between them).  And you can still type the symbol name
in full.

What others think?
