The virtual filesystem that we provide to expose downloaded images will erroneously interpret filenames with redundant path separators such as ".\filename" as an attempt to open the directory, rather than an attempt to open "filename". This shows up most obviously when chainloading from one iPXE into another iPXE, when the inner iPXE may end up attempting to open ".\autoexec.ipxe" from the outer iPXE's virtual filesystem. (The erroneously opened file will have a zero length and will therefore be ignored, but is still confusing.) Fix by discarding any dot or backslash characters after a potential initial backslash. This is very liberal and will accept some syntactically invalid paths, but this is acceptable since our virtual filesystem does not implement directories anyway.
