Check return codes everywhere

[lanurmi]

Some checks for return codes are missing.

Examples: Would you like to add more error handling for return values from "realloc" like in the member function "EBuffer::ScanForRoutines" and from "fprintf" in the function "SaveHistory"? http://efte.svn.sourceforge.net/viewvc/efte/trunk/src/e_search.cpp?revision=1084&view=markup http://efte.svn.sourceforge.net/viewvc/efte/trunk/src/c_history.cpp?revision=1062&view=markup
