Improve reading from FORM for long expressions

Fix unnecessarily slow reading from FORM for long texts, which was
caused by redundant searches of the end marker.

A benchmark test on a desktop PC:
```
import form

with form.open() as f:
    f.write('''
        AutoDeclare Vector p;
        Local F = g_(0,p1,...,p18);
        trace4,0;
        .sort
    ''')
    s = f.read('F')
    print(len(s))
```
The result contains 986841 terms and the text length is 64144664.

python 2.7.13 : 0m4.293s  -->  0m2.621s
python 3.6.1  : 0m4.440s  -->  0m2.549s
pypy 5.7.1    : 0m5.035s  -->  0m3.109s
pypy3 5.7.1   : 0m7.288s  -->  0m4.639s

The corresponding FORM program (with dumping the output to a file) spent
