'''Utility functions for morph.'''
def indent(string, spaces=4):
'''Return ``string`` indented by ``spaces`` spaces.
The final line is not terminated by a newline. This makes it easy
to use this function for indenting long text for logging: the
logging library adds a newline, so not including it in the indented
text avoids a spurious empty line in the log file.
This also makes the result be a plain ASCII encoded string.
