Pasting multiple lines doesn't work

[welash]

When trying to paste multiple lines into an application using linenoise, only the first line is taken. As an example, compiling the example applicacation and trying to paste

test1
test2
test3
test4
test5

into the example application gives:

lash@bill17laptop:~/linenoisepaste/linenoise$ ./linenoise_example
hello> test1
echo: 'test1'
hello>

This seems to be because of the use of TCAFLUSH in enableRawMode and disableRawMode. By changing thos to TCADRAIN, I see the expected behavior:

lash@bill17laptop:~/linenoisepaste/linenoise$ ./linenoise_example
hello> test1
echo: 'test1'
hello> test2
echo: 'test2'
hello> test3
echo: 'test3'
hello> test4
echo: 'test4'
hello> test5
echo: 'test5'
hello>

Here is the patch that I used:

I'm encountering the same problem in gnome-terminal, lxterminal and xterm, and would like to see it fixed. The above patch works for me in gnome-terminal and lxterminal, but acts strangely in xterm (and probably other terminal emulators).
The first line is entered individually, but the subsequent lines seem to be entered "together".

xterm:

hello> test1
echo: 'test1'
test2
test3
test4
test5hello> test2
                 test3
                      test4
                           test5
echo: 'test2
test3
test4
test5'
hello>
