set_pass1_restoreFile() is wrongly defined for iocsh
autosave fails to detect and reject a truncated .sav file, and segfaults if the file was truncated in the middle of an array.
long-string PV's longer than 120 characters are not read to completion, so remaining string content is treated as a new PV name/value.
array PV's whose representation in a .sav file is exactly 119 characters long result in the PV being handled twice, the second time as a scalar with no data. For an array of char, this has had the effect of setting the first element to zero.
.sav files must have a header line. Too sensitive to errors reported in errno. Status PV's restricted to PV_NAME_LEN chars. Blank but not empty lines cause problems.
Not too smart about array PV's changing number of elements.
Kills itself if it can't find its status PV's.
Note that this 3.13-compatible software is not in the form of a module.
