Description of problem:

Reposurgeon fails during certain operations with Python errors due to formatting. This occurs in multiple operations.

Version-Release number of selected component (if applicable):
3.47 1.fc31 from reposurgeon-3.47-1.fc31 @System

How reproducible:
Completely

Steps to Reproduce:
1. Assuming the package is installed, create a directory and run repotool initialize PROJECTNAME, e.g.:

repotool initialize sampleconversion

Respond with "svn" and "git" to the two questions on the to/from systems.

2. Edit the Makefile generated by repotool and add a valid Subversion https repository.

3. In the project directory, run "make stubmap" (which would read the committers from the repo to produce a committer-to-email mapping file of PROJECTNAME.map)
OR
run simply "make"

Actual results:

------------------------------------------------------------
reposurgeon "verbose 1" 'script repos3.opts' "read  <repos3.svn" 'authors read <repos3.map' 'sourcetype svn' 'prefer git' 'script repos3.lift' 'legacy write >repos3.fo' 'write >repos3.fi'

TabError: inconsistent use of tabs and spaces in indentation
make: *** [Makefile:63: repos3.fi] Error 1
------------------------------------------------------------

Expected results:
No errors.

Additional info:
Multiple different statements and errors have occurred; attempting to correct them by modifying formatting in the /usr/bin/reposurgeon file seems to incrementally make them go away if parts of the file are reformatted add/remove tabs/spaces.

There exists a newer (3.48) version from the author's website; however, I don't know how the packaging of this component works.
This is the final version of the product based on python; 4.0 will be written using Go, according to the author's website.
