[PATCH] splitfx: add INDIR and INBASE environment variables |

These are intended to act like `$(@D)' and `$(@F)' in GNU make(1)
and to ease managing temporary files for some effects
(e.g. noiseprof + noisered in sox) for splitfx users.

@@ -99,6 +99,8 @@ dtas-splitfx sets several default environment variables for
commands to
use in targets:
* INFILE - this matches the "infile" directive in the YAML file
+* INDIR - the directory INFILE belongs to
+* INBASE - the basename of INFILE
* TRIMFX - essential, this supplys the necessary sox(1) trim effect to
each track.
* COMMENTS - expands to --comment-file=PATH for sox(1)
