-
-% these two functions are for indenting individual systems
-% - to left-indent a system, apply \pseudoIndent before the music continues
-% - \pseudoIndents is similar, but lets you also indent on the right
-% - both provide an option for changing that system's instrument names
-
-% N.B. these functions
-% - assume application to non-ragged lines (generally the default)
-% - include a manual \break to ensure application at line start
-% - misbehave if called more than once at the same line start
-
-% the parameters of the (full) pseudoIndents function are:
-% 1: name-tweaks
-%      usually omitted; accepts replacement \markup for instrument names
-%      as an ordered list; starred elements leave their i-names unchanged.
-% 2: left-indent
-%      additional left-indentation, in staff-space units; can be negative,
-%      but avoid a total indentation which implies (unsupported) stretching.
-% 3: right-indent
