* Revised ReadChars to restore an attempt to make sure we do not short readdgp_may_be_pointlessdgp2014-02-061-0/+32
| | | | | because of a false notion of limited storage space. The test suite does not appear to demonstrate any case where this matters. Could be an incomplete test suite, or an example of pointless code.
* Revise the Tcl_Append* machinery to tolerate NULL bytes to append.dgp2014-01-271-10/+19
| | | | Then have ReadChars() use that machinery to resize buffer receiving input, rather than invent its own version. Simplify ReadChars() callers.
