Bug: using i\, a\ or c\ at EOF

[aureliojargas]

$ cat bug.sed
i\
$ ./sedsed.py -f bug.sed 

$ ./sedsed.py -e 'i\'

$

The i command was ignored in both -e and -f.

Fixed by the new sedparse parser, see #52.

$ cat bug.sed
i\
$ ./sedsed.py -f bug.sed 
i\

$ ./sedsed.py -e 'i\'
i\

$

Mmmm, but that extra blank line in the output does not seem right.

Indeed, when running the debug, it is adding an extra blank line that it shouldn't:

$ seq 5 | sed -e '3i\'
1
2
3
4
5
$ seq 5 | ./sedsed.py -d -e '3i\' --hide=patt,hold,comm
1
2

3
4
5
$

When the i command is not at EOF, it works as expected:

$ seq 5 | ./sedsed.py -d -e '3i\' -e foo --hide=patt,hold,comm
1
2
foo
3
4
5
$

It seems it is a bug in sedparse, see aureliojargas/sedparse#2
