Add alt code to 1986/hague - fgets()

The reason it is in alt code is because one of the forms of input (see
below) will, although print out correct output, segfault after
outputting the text. That is when one does something like:

    echo foo | ./hague.alt

Whether it might be worth making it the entry itself with a note in the
Makefile and README.md and bugs.md (because it does print out correct
output) can be determined later - or not.

This change required several files to be updated besides the new file
hague.alt.c.

+### Alternate code:
+
+Whereas with some entries the change to `fgets()` (see the [FAQ](/faq.md) for
+details on why this has been done) can be done in the original code this entry
+is more complicated in that although both forms of input show the correct
+output, one form segfaults after the output.
+
+If you wish to use this alternate code, do:
+
+```sh
+make alt
+```
+
+Use `hague.alt` as you would `hague` above. As for which form will segfault
+after outputting the text it is when text is piped into the program. Again see
+the [bugs.md](/bugs.md) file for more details.
