updated for version 7.3.102 Problem: When using ":make", typing the next command and then getting the "reload" prompt the next command is (partly) eaten by the reload prompt. Solution: Accept ':' as a special character at the reload prompt to accept the default choice and execute the command.

is<F4>foo
{'silent': 0, 'noremap': 0, 'lhs': 'foo<C-V>', 'mode': ' ', 'expr': 0, 'sid': 0, 'rhs': 'is<F4>foo', 'buffer': 0}
{'silent': 1, 'noremap': 1, 'lhs': 'bar', 'mode': 'v', 'expr': 1, 'sid': 0, 'rhs': 'isbar', 'buffer': 1}
