64 | * pr: more boundary conditions than a four-legged porcupine | |||
65 | * | |||
66 | * the original version didn't support form-feeds, while many of the ad-hoc | |||
67 | * pr implementations out there do. Adding this and making it work reasonably | |||
68 | * in all four output modes required quite a bit of hacking and a few minor | |||
69 | * bugs were noted and fixed in the process. Some implementations have this | |||
70 | * as the as -f, some as -F so we accept either. | |||
71 | * | |||
72 | * The implementation of form feeds on top of the existing I/O structure is | |||
73 | * a bit idiosyncratic. Basically they are treated as temporary end-of-file | |||
74 | * conditions and an additional level of "loop on form feed" is added to each | |||
75 | * of the output modes to continue after such a transient end-of-file's. This | |||
76 | * has the general benefit of making the existing header/trailer logic work | |||
77 | * and provides a usable framework for rational behavior in multi-column modes. | |||
78 | * | |||
79 | * The original "efficient" implementation of the "skip to page N" option was | |||
80 | * bogus and I substituted the basic inhibit printing until page N approach. | |||
81 | * This is still fairly bogus vis-a-vis numbering pages on multiple files | |||
82 | * restarting at one, but at least lets you consistently reprint some large | |||
83 | * document starting in the middle, in any of the output modes. | |||
84 | * | |||
85 | * Additional support for overprinting via <back-space> or <return> would | |||
86 | * be nice, but is not trivial across tab interpretation, output formatting | |||
87 | * and the different operating modes. Support for line-wrapping, either | |||
88 | * strict or word-wrapped would be really useful and not all that hard to | |||
89 | * kludge into the inln() implementation. The general notion is that -wc n | |||
90 | * would specify width and wrapping with a marker character c and -Wc n | |||
91 | * would add word wrapping with a minimum width n and delimiters c, defaulting | |||
92 | * to tab, blank, and -, and column width. Word wrapping always involves | |||
93 | * painful policy questions which are difficult to specify unless you just | |||
94 | * hardwire in some fixed rules. Think quotes, punctuation and white-space | |||
95 | * elimination and whether you'd do the same thing with a C program and | |||
96 | * something like columninated newspaper text. | |||
