After Tcl/Tk 8.3.3 text and entry widgeds become very
inefficients working with long single lines, (without end of
lines)

e.g this is very inefficient with 8.4.9 version (it was better
with 8.3.3)

text .t
.t insert 1.0 [string repeat "x" 100000]

but this works ok:
text .t
.t insert 1.0 [string repeat "x\n" 100000]
